What does CSG mean in UNCLASSIFIED

How CSG Works

CSG starts with a set of primitive shapes, such as cubes, spheres, and cylinders. These shapes are then combined using boolean operations to create new, more complex objects. For example:

• Union: Combines two or more shapes into a single shape that includes all the volume of the original shapes.
• Intersection: Creates a new shape that represents the overlapping volume of two or more shapes.
• Difference: Subtracts the volume of one shape from another, creating a shape with the first shape's "carved out" where the second shape intersects.

Applications of CSG

CSG has a wide range of applications, including:

• 3D Modeling: Creating complex 3D models for use in movies, video games, and engineering.
• CAD: Designing and manufacturing physical objects, such as parts and tools.
• Architectural Design: Modeling buildings and other structures.
• Medical Imaging: Visualizing and analyzing 3D medical scans.

Advantages of CSG

• Simplicity: CSG uses simple boolean operations, making it easy to create complex models.
• Predictability: The results of CSG operations are predictable, allowing for precise control over the shape of the model.
• Efficiency: CSG can represent complex models with a relatively small number of shapes.

Disadvantages of CSG

• Boolean Complexity: Boolean operations can become computationally expensive for large or complex models.
• Non-Manifold Topology: CSG models can sometimes create non-manifold topology, which can cause problems in some applications.
• Limited Shape Representation: CSG is not well-suited for representing organic or curved shapes.
